UNITED STATES JOHN F. MCCOY, OF BEVERLY, NEW JERSEY.

TlRE-UPSETTER.

SPECIFICATION forming part of Letters Patent No. 227,557, dated May 11,1880.

Application filed February 18, 1880.

7 Beverly, county of Burlington, State of New have invented a new anduseful Im- Jersey of which the 01- provement in Tire-Upsetters, lowingis a specification.

Figure 1 is a rear elevation of the improvement. Fig. 2 is a sectionalelevation taken through the line or a, Fig. 1; and Fig. 3 is aperspective view of the toothed plate.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish tire-upsetters so constructedthat they may be used upon an anvil, and which shall be simple inconstruction and convenient and effective in use.

The invention consists in constructing a tire-upsetter of a treadle, aspring, a jointed standard carrying toothed arms upon its upper end, thebar and keepers for holding the standard erect, and the concaved andtoothed plate for preventing the tire from slipping, all combined andoperating as will be hereinafter fully described.

A represents the anvil. B is the anvilblock, which is made in two parts,or has a slot or opening formed through it to receive a treadle, G.

The treadle 3 is held up by a coiled spring, D, attached to it and tothe base of the anvil A or the upper part of the block B. The rear endof the treadle O is pivoted to the rear side of the block B, and to it,near its rear end, is pivoted the lower end of the standard E, whichpasses up through a strap, F, attached to the rear side of the block B,to keep it in an erect position.

Thestandard E is jointed, so that its upper part can be turned back outof the way when not required for use.

The standard a bar, G, placed upon its rear side and inserted in keepersH, attached to the standard E above E is held erect when in use by andbelow its joint, so that the said bar G can be readily withdrawn toallow the standard E to be turned back out of the way.

Upon the upper end of the standard E are formed two forwardly-projecting arms, I, which extend over the anvil A and have teeth or points J upontheir lower sides to take hold of the tire and hold it while beingupset.

Upon the top of the anvil A is laid a plate, K, which has a squareprojection, L, formed upon its lower side at one end to fit into a holein the anvil A, to keep the said plate K in place.

The middle part, M, of the face of the plate K is concave to give theproper shape to the upset part of the tire.

The end parts of the face of the plate K have in wardly-projecting teethN formed upon them to take hold of the tire and hold it from slippingwhile being upset.

In using the upsetter the tire is heated and has an inwardly-projectingbend or loop formed in it over the horn of the anvil. The looped part ofthe tire is then placed between the arms I, the tire upon both sides ofthe said loop is clamped between the arms I and the plate K, and theloop in the tire is hammered out, shortening the tire more or less,according as a greater or less loop may have been formed in it.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- The combination, with the anvil A, twopart block B,and spring-treadle O, of the pivoted standard E, having toothed armsII,and jointed near the top, the bar Gin keepers, and the toothed plate K,having projection L and concave M, as and for the purpose specified.
